Product Guide
Flex System is the next generation of blade technology with more performance and bandwidth and far more
capability to consolidate and virtualize than previous systems.
Introducing the Lenovo Flex System Carrier-Grade Chassis, a new version of the Flex System chassis that is
designed for the telecommunications industry where tolerance of harsher environments is required. This CarrierGrade Chassis is designed to NEBS level 3 and ETSI certification levels and for operation within Earthquake
Zone 4 areas. The chassis also includes dust filters and -48V DC power operation, as required for many Central
Office telco environments.
The Flex System Carrier-Grade Chassis is shown in Figure 1.
Figure 1. Flex System Carrier-Grade Chassis
Did you know?
The chassis is ASHRAE 4 compliant, meaning it allows normal operation in temperatures of up to 45 °C (113 °F),
with temporary elevated temperature excursions of up to 55 °C (131 °F) for as long as 4 days. This is a key
requirement for industries, such as the telecommunications industry where the harsher environments in central
offices (COs) require IT equipment that operate on -48V DC power and can tolerate higher temperatures.

Key features
Similar to the Enterprise Chassis, the Flex System Carrier-Grade Chassis is a simple, integrated infrastructure
platform that supports a mix of compute, storage, and networking resources to meet the demands of your
applications. The solution is easily scalable with the addition of another chassis with the required nodes. With
Lenovo XClarity Administrator, multiple chassis can be monitored from a single window. This flexible 14 node,
10U chassis is designed for a simple deployment now and to scale to meet your needs in the future.
Flexibility and efficiency
The 14 bays in the chassis allow the installation of compute nodes, with I/O modules in the rear. A single
chassis or a group of chassis can be fully customized to the specific needs of the computing environment. IT
can meet the needs of the business by using a single system across multiple operating environments.
The system monitors and manages power usage on all major chassis components so you have total control
over power consumption. With -48V DC power supplies and N+N or N+1 redundancy, the chassis integrates
into telco environments, such as those in central offices. The chassis design also optimizes cooling with cooling
zones within the chassis. There is sufficient cooling throughout the chassis to allow normal operation in
temperatures of up to 45 °C (113 °F), with temporary elevated temperature excursions of up to 55 °C (131 °F) for
as long as 4 days.
The system manages the fan modules based on the node configuration within the chassis. Therefore, the
system can increase the speed of certain fan modules to cool potential hot spots and use lower speeds for
other fan modules where appropriate.
Easily scalable with simple administration
Because the Carrier-Grade Chassis is an all-in-one solution, it is designed for growth from a single chassis to
many. Adding compute or networking capability is as simple as adding nodes or modules. The simple, highly
integrated management system allows you to use the Chassis Management Modules that are integrated into
each chassis to administer a single chassis, and the new Lenovo XClarity Administrator offers agent-free
hardware management for compute nodes and networking.
Designed for multiple generations of technology
The Carrier-Grade Chassis is designed to be the foundation of your IT infrastructure now and into the future.
Compute performance requirements are always on the rise and networking demands continue to grow with
rising bandwidth needs and a shrinking tolerance for latency. The chassis is designed to scale to meet the
needs of your future workloads, and offers the flexibility to support current and future innovations in compute,
storage, and networking technology.

Supported numbers of compute nodes
The actual number of compute nodes systems that can be powered on in a chassis depends on the following
factors:
The TDP power rating for the processors that are installed in the compute nodes.
The number of power supplies that are installed in the chassis.
The power redundancy policy that is used in the chassis (N+1 or N+N).
The table in the Power Supplies section provides guidelines about the number of compute nodes that can be
powered on in the chassis based on the type and number of power supplies that are installed.

I/O architecture
Each half-wide compute node (such as the Flex System x240 M5 Compute Node) has two adapter slots. The
adapter slots in each compute node route through the chassis midplane to the switch bays. The architecture
supports up to eight ports per adapter. The following figure shows how two-port adapters are connected to
switches that are installed in the chassis.
Figure 5. Logical layout of the interconnects between two-port I/O adapters and I/O modules
A four-port adapter doubles the connections between each adapter and switch pair (for example, a four-port
adapter in A1 in each compute node routes two connections to switch 1 and two connections to switch 2).
The following figure shows how four-port adapters are connected to switches that are installed in the chassis.

Chassis Management Module
The Chassis Management Module 2 (CMM2) provides single-chassis management in the Carrier-Grade
Chassis. The CMM is used to communicate with the integrated management module (IMM) controller in each
compute node to provide system monitoring, event recording and alerts, and to manage the chassis, its
devices, and the compute nodes.
The chassis has one CMM installed standard but supports two CMMs for redundancy. If one CMM fails, the
second CMM can detect its inactivity and activate to take control of the system without any disruption. The
CMM is central to the management of the chassis and is required in the Carrier-Grade Chassis.
The following table shows the ordering information.

corresponds to the optional second CMM which provides redundancy.
The following figure shows the CMM. For more information about the location of the CMM in the chassis, see
Figure 3.

The CMM provides the following functions:
Power control
Fan management
Chassis and compute node initialization
Switch management

Security policy management
Role-based access control
Support for up to 84 local CMM user accounts
Support for up to 32 simultaneous sessions
The CMM has the following connectors:
USB connection. This connection can be used for insertion of a USB media key for tasks, such as
firmware updates.
10/100/1000 Mbps RJ45 Ethernet connection to connect to a management network. The CMM can be
managed via this Ethernet port.
Serial port (mini-USB) for local command-line interface (CLI) management. Use serial cable 90Y9338 for
connectivity.
The CMM features light-emitting diodes (LEDs) that provide the following information:
Power-on LED
Activity LED
Error LED
Ethernet port link and port activity LEDs
The CMM also incorporates a reset button, which resets the CMM to its default condition when pressed. It has
the following functions, depending on how long the button is pressed:
When the button is pressed for less than 5 seconds, the CMM restarts.
When the button pressed for more than 5 seconds, the CMM configuration is reset to the manufacturing
defaults and the CMM restarts.
The CMM supports a web-based graphical user interface (GUI) with which CMM functions can be performed
within a supported web browser. You can also perform management functions through the CMM CLI. The webbased GUI and the CLI are accessible via the single RJ45 Ethernet connector on the CMM or from any other
system that is connected to the same (management) network.
The CMM has the following default static IPv4 address. By default, the CMM is configured to respond to
Dynamic Host Configuration Protocol (DHCP) first before its static IPv4 address is used:
IP address: 192.168.70.100
Subnet: 255.255.255.0
User ID: USERID (all capital letters)
Password: PASSW0RD (all capital letters, with a zero instead of the letter O)
The CMM does not have a fixed static IPv6 IP address by default. Initial access to the CMM in an IPv6
environment can be performed by using the IPv4 IP address or the IPv6 link-local address. The IPv6 link-local
address is automatically generated based on the Media Access Control (MAC) address of the CMM.
The CMM is the key component that enables the integrated management network. Internally, the CMM has a
multiple port L2 1Gigabit Ethernet switch with dedicated links to all 14 node bays, all four switch bays, and the
second CMM, if installed. These connections are all point-to-point, which ensures dedicated bandwidth. The
1GbE links are full-duplex, fixed speed (not auto-negotiate) links. The 1 GbE management network is accessible
only by each node's management controller, each switch module's management interfaces, and the CMM. This
design permits the separation of the management network from the data network.
The CMM has a high-security policy that is enabled by default, which means that the following policies are
enabled by default:
Strong password policies with automatic validation and verification checks.
Required update of the default passwords after the initial setup.
Only secure communication protocols, such as SSH and SSL. Unencrypted protocols, such as HTTP,
Lenovo Flex System Carrier-Grade Chassis
13
Telnet, and SNMPv1, are disabled.
Certificates to establish secure, trusted connections for applications that run on the management
processors.

Power supplies
A maximum of six power supplies can be installed in the Carrier-Grade Chassis. The chassis currently supports
the -48V DC power supply option. Model DCx has two power supplies standard. The ordering part number and
feature code is listed in the following table.

The -48V DC power supply operates at -48V to -60 V dc (nominal) and has a Molex 1060 Power Connector. The
power supply ships with one 2.0m DC power cord (FRU part number 69Y1652)
The chassis allows configurations of power supplies to give N+N or N+1 redundancy. Although a chassis can
operate on only three power-supply units (PSUs) with no redundancy, N+1 or N+N is advised. Three power
supplies (or six with N+N redundancy) allow for a balanced three-phase configuration.
All power supply modules are combined into a single power domain within the chassis, which distributes power
to each of the compute nodes, I/O modules, and ancillary components through the Carrier-Grade Chassis
midplane. The midplane is a highly reliable design with no active components. Each power supply is designed
to provide fault isolation and is hot swappable.
The following figure shows the compute node bay numbering (left) and power supply bay numbering (right).
Figure 9. Power supply bay numbering
The following table shows the number of compute nodes that are supported in the chassis based on the number
of power supplies that are installed and the power redundancy policy that is enabled (N+1 or N+N).
In this table, the colors of the cells have the following meaning:
Green cell: Supported with no restrictions as to the number of compute nodes that can be installed
Yellow cell: Supported but with restrictions on the number of compute nodes that can be installed.
Note: These tables assume the chassis includes identical compute nodes. For more complex configurations,

Fan modules
The Carrier-Grade Chassis supports up to a total of 10 hot-swap fan modules: two 40 mm (1.57 in) fan modules
and eight 80 mm (3.14 in) fan modules.
The two 40 mm fan modules (which ship with the chassis) distribute airflow to the I/O modules and CMMs. The
80 mm fan modules distribute airflow to the compute nodes through the chassis from front to rear. Each 80 mm
fan module contains two 80 mm fan modules, back-to-back at each end of the module, which are counterrotating. The following figure shows the 80 mm fan module.
Figure 10. 80 mm fan module
Four 80 mm fan modules are installed standard in the DCx chassis model. The maximum number of 80 mm fan
modules that can be installed is eight. Ordering information is shown in the following table. When the modules
are ordered as a part number, they are supplied as a pair. The feature codes include one fan.

The 80 mm fan modules are populated, depending on the nodes installed. To support the base configuration
and up to four nodes, the standard model ships with four 80 mm fan modules and two 40 mm fan modules
preinstalled. There are separate left and right cooling zones for the nodes. Fan modules must be installed in
pairs, as shown in the following figure. If there are insufficient fan modules for the number of nodes installed, the
compute nodes might be throttled to balance heat generation and cooling capacity.

Air filters
The Carrier-Grade Chassis includes an airborne contaminate filter that is fitted to the front of the chassis in two
components. The main filter assembly covers the compute nodes and a secondary filter assembly covers the
1U air-inlet at the bottom of the chassis.
Each filter assembly includes 6 mm polyurethane filter media that should be removed, inspected, and replaced
on a regular basis. The filter media pieces are usable parts and are not covered under the terms of the warranty.
Lenovo recommends the following service intervals:
For low dust, low foot traffic environments, inspect and clean the filter media every 3 months and replace
the filter media every 6 months.
For moderate dust, moderate foot traffic environments, inspect and clean the filter media every 6 weeks
and replace the filter media every 3 months.
For heavy dust, heavy foot traffic environments, inspect and clean the filter media every 2 weeks and
